Gasoline for aircraft use

A method for preparing a piston-driven engine blended aviation gasoline composition comprising:

• a. providing a blendstock for automotive gasoline, wherein the provided blendstock for automotive gasoline comprises an oxygen content in an amount that ranges from 0% by weight to 0.06% by weight, and a lead content in an amount that ranges from 0 grams per gallon to 0.03 grams per gallon;
• and then
• b. adding an octane enhancer and a pressurant to the provided blendstock for automotive gasoline, thereby making the piston-driven engine blended aviation gasoline composition,
• wherein the method does not comprise a step of adding an additional amount of oxygenate or lead to the provided blendstock for automotive gasoline and does not comprise a step of adding an additional amount of oxygenate or lead to the piston-driven engine blended aviation gasoline composition;
• wherein the piston-driven engine blended aviation gasoline composition comprises an oxygen content, contributed by ethanol, in an amount that ranges from 0% by weight to 0.06% by weight, based on the total weight of the piston-driven engine blended aviation gasoline composition and the total oxygen content weight contribution of ethanol present in the piston-driven engine blended aviation gasoline composition;
• wherein the piston-driven engine blended aviation gasoline composition comprises an oxygen content, contributed by methanol, in an amount that ranges from 0% by weight to 0.06% by weight, based on the total weight of the piston-driven engine blended aviation gasoline composition and the total oxygen content weight contribution of methanol present in the piston-driven engine blended aviation gasoline composition;
• and
• wherein the piston-driven engine blended aviation gasoline composition comprises lead in an amount that ranges from 0 grams per gallon to 0.03 grams per gallon of the piston-driven engine blended aviation gasoline composition;
• and
• wherein the piston-driven engine blended aviation gasoline composition comprises an oxygen content in an amount that ranges from 0% by weight to 0.06% by weight, based on the total weight of the piston-driven engine blended aviation gasoline composition and the total oxygen content weight of all oxygenates present in the piston-driven engine blended aviation gasoline composition.
